ABSTRACT:
A distributor wheel 20 comprises, downstream of each outlet aperture (24, 25) of its channels (22, 23), in relation to the direction of the projection of particles, a member (30, 33, 34) fixed for rotation with the wheel (20) and making it possible to form, at the end of the guide face of each channel (22, 23), a stable protective cushion composed of the particles themselves and extending the stable self-protection layer (28), and to eliminate the contact force between the particles and the wheel (20) before ejection and projection of the particles onto the target.
